MACHINE FOR DRESSING STONE.

SPECIFICATION forming part of Letters Patent No. 396,044, dated January8, 1889.

Application led July 1 3, l 88 8.

To aZZ whom, it may concern..-

Beit known that I, FRANK MANNING, a citizen of the United States,residing at Nar-berth, in the county of Montgomery, State ofPennsylvania, have invented a new and useful Improvement in Machines forDressing Stone, which improvement is fully set forth in thew followingspecification and accompanying' drawings.

My invention relates to improvements in machines for dressing stone 5and the objects of the invention are to provide means for adjusting thecarriage carrying the cutters vertically and horizontally, and also formoving the trucks carrying the stone at a right angle to the movement ofthe carriage while under the action of the cutters, whereby the stone isdressed in a rapid and perfect manner.

A further object is to provide mechanism which will operate the carriagecarrying the cutters and also the stone-carrying trucks in suoli mannerthat the vertical and horizontal movement of the carriage will operatein combination with the movement of the stone-carrying trucks in orderto insure the proper working of the machine.

The invention consists in a carriage carrying cutters and mechanism forimparting to the carriage a horizontal and vertical movement 5 further,in a carriage carrying cutters', mechanism for operating said cutters,and mechanism for moving the carriage vertically and horizontally;further, in the combination, with a carriage carrying cutters, mechanismfor operating said cutters, and mechanism for moving the carriagevertically and horizontally, of a mechanism for moving the stone whileunder the action of the cutters, said movement being in accordance withthe movement of the carriage; further, the invention consists in thedetails of construction, combination, arrangement, and adaptation of parts for service, as hereinafter described and claimed.

Figure 1l represents a side elevation of a stone-dressing machineembodying my invention. Figs. 2 and 4L represent a side elevation ofportions thereof, Fig. et being on an enlarged scale. Fig. 3 representsa view of the carriage detached, on an enlarged scale.

Serial No. 279,854. (No model.)

Similar numerals of reference indicate corresponding parts in theseveral figures.

Referring to the drawings, the numeral l represents two standards,posts, or uprights, each of which has a vertical passage or slot, 2,therein., and one of said posts carries guidepulleys 3, as shown. In thepassage of slot 2 is adapted to be received a frame, et, consisting oftwo horizontal bars connected together and to said frame, which I willterm the carriage-frame,7 is adapted to be moved vertically in theslotted uprights by means of screws 5, which pass through said frame andat their upper ends carry bevel gear-wheels 6, meshing with bevelgear-wheels 7, and a shaft, 8, having its bearings in short uprights 8X,secured to the slotted uprights. From this construction it is evidentthat by revolving the shaft S motion is imparted to the screws, whichengage the frame, causing said frame to move vertically.

The carriage-frame carries at one end the guide-pulley 9, and at theopposite end the guide-pulleys 9X and driving-pulleys 9.

10 represents the carriage, which is provided with openings 10 toreceive the bars of the frame, and journaled in its upper portion is theshaft ll, to one end of which is affixed the crank-wheel l2, to thewrist-pin of which is connected a rod, 13, carrying' the spring 14,connected by means of a belt, 14X, with the cutter l5, moving in guidesor ways 16 on the carriage. To the opposite end of the shaft ll isconnected a clutch-pulley, 17, and IS represents the clutch operated bythe lever 19 to cause said pulley to revolve the shaft ll or throw thesame out of operation, as desired. The carriage also carriesguidepulleys 17 X. rFhrough a screw-threaded opening in the carriagepasses the screw 20, which revolves in the slotted post and carries apulley, 2l, adapted to be driven by means hereinafter described foroperating the screw and causing the carriage to travel horizontally.

From the foregoing it will be seen that the carriage is capable of avertical and horizontal travel or movement.

22 represents posts or uprights, in which is mounted a shaft, 23,carrying the drivingpulleys 24: and the gear-wheels 25 and 26, re-

IOO

spectively, of different diameters, which gearwheels are capable of ahorizontal or shitting movement in the shaft by means ol' theconnecting-key 27, engaging a keyway in said shalt and having alfastening-screw, 2S.

Il rejn'esent uprights, in which are mounted a shatt, 30, carrying thegear-wheels 2:31 and 32, respectively, of different diameters, which areadapted to mesh with the gear-wheels 25 and 2 0 for imparting differentrates ol speed to the sha 3 30. On the shat't 3l) is also adriving-pulley, a3, for driving the screw-operating pulley 2l, and. saidshaft also carries a gear-wheel, 3l, engaging a rack, 35, whichconnected with the stone-carryii'ig trucks 3l), moving on tracks 3T.

From the described construction it is evident thatthe stone-carryingtrucks are moved, and also the carriage, by means oll the horizontalscrew, and also that the said trucks and carriage travel at the properrate of speed. It will also be seen that by shifting the gearwheels onthe driving-shaft the carriage and j trucks may be caused to travel atrilitli'erent rates of speed, as desired, because of the dit Ierence 'indiameters of the meshing gearwheels.

The operation is as follows: The stone to be dressed is placed upon thetrucks and the carriage-frame is adjusted by means of the verticalscrews to bring the carriage near the stone, in order that the cuttersmay operate upon the same. The crank-wheel is then operated through themedium of the drivingbelts passing over the pulleys, shown, causing thecutters to strike the stone with force, the proper stroke being producedby means et' the spring. The carriage is moved horizontally by means ofthe screw passing therethrough, and the stone is caused to travel underthe action of the cutter by means oit' the gear-wheels and raclc.

It will thus be seen that a machine constructed and opcratingasdescribed will dress a stone in a very short time and in a perfectmanner.

l'l'aving thus described my invention, what .l claim as new, and desireto secure by Letters Patent, is-

'l. In a stone-diessing machine, the combination ot' standards oruprights, a carriageirame carried by said uprights, vertical travelingscrews engaging the i'raine for adjusting said l` rame vertically, acarriage mounted on said frame, a screw in the frame for cansingl thecarriage to travel transversely, a pulley on said screw, a transverseshaft mounted in the uprights carrying a pinion and pulley, a bandpassing over the pulleys on the shat't and screw, and a stone-carryingtruck. provided with a rack adapted to mesh with the pinion on, thetransverse shaij't, said parts being arranged and operatingsubstantially in the manner and for the purpose descrilwd.

2. ln a stone-dressing machine, the eombination oi' the posts oruprights, the carriagei'rame mounted therein, the pulleys carried by theframe, the carriage carrying the cutting mechanism mounted on saidframe, the
